IMPROVEMENT IN LAMP-STOVES.

Specification forming part of Letters Patent No. 175,932, dated April 11, 1876 application filed March 6, 1876.

To all whom it may concern Be it known that I, JOHN WARD COLE, of Brampton, Peel, in the Province of Ontario and Dominion of Canada, have invented a new and Improved Lamp-Stove, of which the following is a specification:-

Figure 1 represents a top VlGW, and Fig. 2 a vertical transverse section, of my improved lamp-stove on line 0 0, Fig. 1.

Similar letters of reference indicate corresponding parts.

My invention relates to improvements in cooking-lamps, by which the heating capacity of the same is increased and the lamp easily kept clean and in perfect working order.

The invention consists mainly of the watercompartments for cooling the wick-tubes arranged above the oil-receptacle, and provided with air-chambers between and at each side of the wick-tubes, for the increased supply of air to the flames. A self-feeding water reservoir or tank keeps up the supply of water around the wick-tubes.

A water receptacle or compartment, 0, of considerable depth, is arranged immediately above the oil-reservoir A, for cooling the wicktubes D, that extend from the oil-reservoir inupward direction through the water-compartment to suitable height above the same. The water-compartment O is supplied with water to cool the wick-tubes, from a water-tank, O, of suitable size, that is attached to the side of the water-compartment, and arranged with a small exit-pipe in such a manner that the water is kept in the same automatically at a certain level around the wick-tubes, supplying the water evaporated by the heating of the same, and keeping, thereby, the wicktubes cool for a longer period without the ne cessity of continually refilling the water-compartment.

- In the water-compartment are arranged at the outer sides, and intervening between the wick-tubes, open air-chambers E, that are connected, by side and bottom channels or tubes E, with the outer air, the central airchamber receiving air through a vertical tube passing centrally through the oil-reservoir, while the side air chambers are supplied through horizontal side tubes passing through the water-compartment.

A continual supply of fresh air is thus conducted to the wick-tubes, so that a more complete combustion of the oil is obtained, and a greater degree of heat produced in consequence thereof.

The arrangement of the air-chambers in the water-compartment and the free supply of air to both sides of the flame by the air-chambers give the great advantage of allowing the water compartment to be made atconsiderable depth, so that the more perfect cooling of the wick-tubes is produced by the greater quantity of water therein.

The air-chambers may be made somewhat higher than the walls of the water-compartment, and serve, also, as support for the perforated tin covering-plate F, and for the burners with the chimneys, without requiring bars or other supports across the wick-tubes.

The horizontal air tubes or channels E admit the arrangement of the spurred wick-lifters G, that turn in supports b of the air-chamber, the water-compartment extending immediately above the wick-lifters along the wicktubes, to keep the parts above the lifters cool, as shown in Fig. 2.

The water may be drawn off from the water-compartment by a corked tube or stopcock, d, near the bottom of the same, to allow the drawing oii' of the water and replacing it by clean Water.

The lamp-stove requires no packing for the wick-tubes, is readily kept clean and in order, and burns by means of the increased supply of air-to the flames with greater economy and efficacy Having thus described my invention, I claim as new and desire to secure by Letters Patcut- 1, A lampstove provided with a watercompartment above the oil receptacle, and air -chambcrs in the water-compartmentat both sides of the wick-tubes, theair-chambers being supplied with air through side and bottom channels or tubes, substantially as described.
